抄録

The working face at Miike coal mine have been removed into the thick seam area over 3 meter gradually since 1950-1951. To work this seam throughly, several mining methods were investigated, then the slicing system was applied in Mikawa pit, while self advancing powerd roof support was introduced to Miyaura pit.<BR>It had been generally believed that the working height of long wall face in low dip was up to nearly 2.8 meter, however, after extensive examinations, we had developed the self advancing support using mighty hydraulic props of higher yielding load, there by we have succeed in getting coal seam over 3 meter throughly at same time.
